Product Description:
The Pacific Scientific 55NM81-200-2 is a flange mounted torque motor that is part of the PMDC Low Inertia Servomotors family. It has an IP54 rating, a rated torque of 200 Nm, and a rated speed of 81 rpm. This 3 phase (Three Phase) motor needs 380 V (Volts) at 50 Hz (Hertz) to work and features a coiled rotor design that cools the air. The 55NM81-200-2 is from Pacific Scientific acts as a highly efficient servo from the popular 55NM lineup. The 55NM81-200-2 engineered by Pacific Scientific is tailored for industrial tasks that require quick positioning. Furthermore, this torque motor is super ideal for incremental accurate motion control.
It comes with an assessed current of 23.2 Amperes. Moving on, this motor comes with a voltage rating of 48 V (Volts). In short, this servo comes with a torque-constant (medium) winding. This makes it a good choice for tough industrial automation settings. The 55NM81-200-2 has an air outlet and inlet cooling system with baffles that improves airflow and helps keep the device at the right temperature even when it is running continuously or at high speeds. The motor's magnet is composed of Alnico V, which is noted for having strong magnetic qualities.
This helps the 55NM81-200-2 motor work consistently. This motor doesn’t come with an analogue tachometer. Similarly, it does not come with an optical encoder. This is why, customers may have to add additional feedback devices plugins as needed. The shaft assessed diameter at the drive-end bearing journal is assessed between 0.469 to 0.531 inches. The Pacific Scientific 55NM81-200-2 servo motor is a great option for industrial automation systems that need accurate motion control, management and strong construction since it is dependable, fast, adaptable, configurable.
